Abstract
The invention discloses an organic fertilizer alkalinity regulator and a preparation method thereof. The regulator is formed by adsorbing acidic substance with adsorbent. The preparation method of the organic fertilizer alkalinity regulator has the advantages of simple method, low manufacture cost and convenient use, can regulate the PH value of organic fertilizer effectively and facilitates transportation and storage.
Description
Technical field
The present invention relates to a kind of organic fertilizer alkalinity regulator, belong to agricultural---fertilizer field.
Background technology
Soil and fertilizer are two big fundamentals of agriculture production.Since the eighties in last century, China can plough the soil and use chemical fertilizer in a large number, the result causes that land deterioration, soil fertility descend, agricultural ecological is unbalance, deterioration in quality, organic matter are subjected to different pollutions with beneficial microorganism minimizing, water resources and environment, makes human health be subjected to potential and threatens.
Organic fertilizer not only contains macroelement and various trace elements such as the required nitrogen of plant growth, phosphorus, potassium, the more important thing is also have the water that improves soil, multiple function such as fertilizer, gas, heat condition.Therefore, the novel organic fertilizer of research and development is vast agricultural sciences worker's a important topic.At present the report of relevant fertilizer and preparation method thereof is more, as the patent No. be 200710014508.7 and the patent No. be 2005101337.3 Chinese invention patent.
But the part fertilizer that use with chicken manure, cattle manure production in the north (particularly Beijing area), the pH value of biological organic fertilizer surpass 8.0, and the content of organic matter is lower than 30%, are difficult to reach the requirement of Ministry of Agriculture's organic fertilizer standard (NY525-2002).Address this problem, general use strong acid such as acidic substance such as nitric acid, phosphoric acid or glacial acetic acid to wait to regulate acidity, but, these acidic substance not only cost are higher, and corrodibility is strong, and poor stability is not easy to transportation and storage especially, be unfavorable for also that peasant household dilutes these acidic substance and with the operation that is mixed of fertilizer, operator easily burn.
Summary of the invention
The objective of the invention is to be to provide a kind of organic fertilizer alkalinity regulator and preparation method thereof, the conditioning agent preparation method is simple, and production cost is low, can effectively regulate the pH value of fertilizer, improves the organic content of fertilizer, and is convenient to transportation and storage.
For achieving the above object, the present invention adopts following technical scheme:
A kind of organic fertilizer alkalinity regulator comprises sorbent material and acidic substance, and acidic substance are adsorbed on the sorbent material.
The present invention also provides a kind of preparation method of organic fertilizer alkalinity regulator, and described method comprises following a few step:
(1) chooses sorbent material and acidic substance;
(2) acidic substance are adsorbed onto on the sorbent material;
(3) the sorbent material filter-press dehydration that will be adsorbed with acidic substance to water content by weight is below 40%, forms organic fertilizer alkalinity regulator.
Described acidic substance can be to utilize fermentation technique to produce one of mother liquor of medicine, nutritive food or feed (as Methionin), and its pH value is 2-3; Not only cost is low to utilize the residual organic acid of mother liquor decolorization (amino acid is main as Methionin), and has solved mother liquor decolouring treatment of wastes produced problem.Compare with adopting strong acid fully, residual its corrodibility of organic acid of mother liquor decolorization is low, safe, and product can be applied to the organic farm products production process.
The preferred gac of described sorbent material because the major ingredient of gac is as organic carbon (C), therefore can provide organic for soil and crop, and its strong adsorptivity possesses water conservation, nutrient preserving capability energy when being beneficial to the fermentation mother liquor decolouring in soil.The granularity of gac is 100 orders or 200 orders, preferred 200 orders.Sorbent material can also be the Calcium hydrogen carbonate or the powdery peat composed of rotten mosses.Adopt gac or Calcium hydrogen carbonate, can be directly used in the mother liquor decolouring, gac or Calcium hydrogen carbonate can adsorb not only that coloring matter reaches the purpose of mother liquor decolouring in the mother liquor, and have adsorbed the acidic substance in the mother liquor, can satisfy the needs that fertilizer is transferred basicity.
Potential of hydrogen situation according to different organic fertilizer products, organic fertilizer alkalinity regulator is added in the organic fertilizer product, stir, detect the pH value of organic fertilizer product with acidometer, the consumption that fertilizer pH value is reduced to 8.0 organic fertilizer alkalinity regulators when following is the suitable consumption of this organic fertilizer alkalinity regulator.Also organic fertilizer alkalinity regulator directly can be joined the potential of hydrogen that is used for controlling fertilizer in the supplementary material of organic fertilizer production, it is to utilize the adsorptivity of sorbent material by reducing the ammonia volatilization of fermenting process that this method also has a benefit, reaches and protects the nitrogen effect.
The present invention prepares by physical adsorption techniques, the preparation method is simple, particularly the acidic substance of Shi Yonging are the organic acidity material that utilizes fermentation technique to produce to contain in the mother liquor of medicine, nutritive food or feed (as Methionin etc.), production cost is low, and the own organic content of conditioning agent abundant (organic content 〉=60%) when being sorbent material with the gac can improve the organic content of fertilizer.And acidic substance of the present invention are to be adsorbed on the sorbent material, with adopting liquid strong acid, be more convenient for transportation, the operation that stores and be mixed, and be mixed easily evenly, can effectively regulate the pH value of fertilizer, make fertilizer reach basic for neutral.
